The ms = 0.5645 and mk=0.1113 for a 30 n box on level ground. what level force is needed to start the box moving

16.935 N

Explanation:

In order to make the box start moving, the level force applied on the box (F) must be greater than the force of static friction that keeps the box at rest, which is equal to

where

is the coefficient of static friction

(mg) = 30 N is the weight of the box

Therefore, the condition for F must be:

So, the applied force must be greater than this value.
